Automatic fire extinguishing device for automobile

Abstract

The invention relates to an automatic fire extinguishing device for an automobile. The automatic fire extinguishing device comprises fire extinguisher devices mounted in an automobile cabin body at fire-hazardous parts of an engine cabin body, wherein each fire extinguisher device comprises a box body; a closed containing cavity for storing a fire extinguishing agent is formed in the lower part of each box body; a fire extinguishing control device is arranged at the upper part in each closed containing cavity; the fire extinguishing device is arranged in the engine cabin body of the automobile; when fire happens in the engine cabin body of the automobile, a fire detector detects a fire happening signal and sends the signal to a control chip; the control chip is used for switching on a gas generator, so that pressure is generated in a fire extinguishing agent container, and a sealing film on a nozzle is punctured to spray a liquid fire extinguishing agent out of the nozzle through a flow guide pipe for fire extinguishing.
